Although I measured out the screw holes of my my Pacifica jack plate to be a couple mm wider than this items supposedly measured center-to-center, it fit perfectly - which was a relief. It's much better than the stock plastic jack plate, which got brittle with age and from tightening the securing nut.

It also blends in better - it's a darker black than the grayish black of the old plastic. In fact, it's so black that I thought to myself, how more black could it be? And I answered myself, "none more black."

I installed mine on an Ibanez AF55 Artcore jazz guitar & it worked well. The wood on the guitar cracked a little, due to my stepping on the cable & yanking-out the jack (mostly sideways).

I had to reshape the plate just a small amount, in order for it to fit the contour of the guitar side. Here's how I did it:

I ended up wrapping it in a bath towel, setting it down on concrete sidewalk, and hitting it with a rubber mallet (once or twice, with moderate blows). The material was at the right amount of softness to flatten slightly. Metal plate did not crack. Also, the paint stayed on perfect.

Be sure to drill out your hole in the wood of the guitar, so that the entire jack will go through.

If I need to ever work on the jack, I now have the convenience of doing so, thanks to the plate!
